In the immediate future, UConn needs Clemson and Florida St. to join the SEC. That would open the door to a UConn ACC move. That is it. That is the only move left on the board for UConn. This, btw, is the best possible outcome for UConn. The football is not so good that UConn can't get competitive there now and with a little work, it's conceivable that the ACC could be the best basketball conference in America without a ton of work.
P.S. - I am aware that leaving the ACC before the current tv contract is up in 2036 and leaving early would result in a massive penalty. "To bolt the ACC, any school would need to pay an exit fee of
three times its annual revenue (approximately $120 million) and would need to navigate the grant in media rights to the ACC to be able to broadcast future games."
I hope this wasn't linked already - AP article on the ACC and Florida St. perspective on leaving.
